Charge vs Time
Formule
Electrical Charge
Electric charge is the fundamental quantity that defines the amount of electricity transferred.
Formula
Q = I * t
where I is the current in amperes and t is the time in seconds. One coulomb equals one ampere flowing for one second.
Exemple Résolu
A circuit carrying 5 A for 60 seconds.
- 01Q = I * t
- 02Q = 5 * 60
- 03Q = 300 C
- 04In mAh: 300 / 3.6 = 83.33 mAh
Questions Fréquentes
What is the charge of one electron?
The elementary charge is approximately 1.602 x 10^-19 coulombs. One coulomb equals about 6.24 x 10^18 electrons.
What is the difference between coulombs and ampere-hours?
1 Ah = 3600 C. Ampere-hours are commonly used to rate battery capacity.
Is charge conserved?
Yes. Electric charge is conserved in all physical processes. Charge cannot be created or destroyed, only transferred.
